    Mechanistic Insights into Defect-Assisted Carrier Transport in Bismuth Vanadate Photoanodes

    No full text
    Understanding defect-assisted carrier transport is critical for optimizing the performance of solar water splitting devices. Here we analyze the mechanism of two distinct types of point defects, oxygen vacancies and hydrogen donors, in defining carrier transport and thus the photoelectrochemical (PEC) behavior in bismuth vanadate (BiVO4). While the conventional hydrogen annealing brings hydrogen donors as a dominant defect, we introduce a novel carbon monoxide treatment that does not introduce hydrogen but only generates more oxygen vacancies. Combined with PEC and solid-state transport characterizations, it is revealed that oxygen vacancies are more effective than hydrogen donor to improve electron transport both within BiVO4 domains and along structural boundaries, thus yielding larger front-illuminated photocurrent, larger film conductivity, and smaller polaron hopping barrier. This study provides mechanistic insights into defect engineering that can guide novel approaches to overcoming charge transport limitations in low-mobility semiconductors

    Bank Accounting Regulations, Enforcement Mechanisms, and Financial Statement Informativeness : Cross-Country Evidence : Cross-Country Evidence

    No full text
    We construct measures of accounting regulations and enforcement mechanisms that are specific to a country's banking industry. Using a sample of major banks in 37 economies, we find that the informativeness of banks’ financial statements, measured by the value relevance of earnings and common equity, is higher in countries with stricter bank accounting regulations and countries with stronger enforcement. These findings suggest that superior bank accounting and enforcement mechanisms enhance the informativeness of banks’ financial statements. In addition, we find that the effects of bank accounting regulations are more pronounced in countries with stronger enforcement in the banking industry, suggesting that enforcement is complementary to bank accounting regulations in achieving higher value relevance of financial statements. Our study has important policy implications for bank regulators.</p
